SPRING OILER.

Application-filed November 23 1923. Serial No. 676,638.

To aZZw/wm it may concern.

Be it known that I-Vv1LLIAM H. BROWN, a citizen of the United States of America, and a-resident of'Glereland, county OfGuyahoga, and State of Ohio,- ha-ve'invented certain new and useful Improvements in Spring Oilers, of which the following'is a full and clear specification.

This invention-has relation to that type of spring oiler which consists essentially of a cup or receptacle which is adapted to be detachably attached to the top leaf of a spring by a spring clamp, the arrangement being such that the vibration of the spring due to the running of the vehicle will cause the oil to splash or surge out of the receptacle and run down on the spring and seep in between the leaves thereof, as more fully hereinafter set forth.

In the drawing V Fig. l is a perspective view of the device applied to a portion of a multi-ply leaf spring;

Fig. 2 is a transverse sectional view thereof;

Fig. 3 is a perspective view of the device with the cover removed;

Fig. t is a plan view, with the cover re moved, showing the closure spring in hori' zontal section; and

Figs. 5 and (S are views of modifications.

lin the drawing, 5 designates the oil-receptacle which is a metal casing, desirably of elliptical form in horizontal section. This receptacle is fastened by means of a pair of rivets 6 to the upper face of a clip which is adapted to grasp the-edges of the top leaf of the spring. This clip consists of a flat plate 7 having its ends curled down to form springanembers 7 which are adapted to spring over and clasp the edges of the top leaf of the spring. The plate 7 of this clip fits down closely against the top face of the spring. Friction prevents the holding clamp from working along the spring, thus insuring proper anchorage to the point where the spring is applied.

The receptacle has a vertical external oilchannel 8 formed in each end, these channels being desirably formed by simply pressing in the metal wall of the. receptacle. These channels are open at their upper ends as well as their lower ends. The receptacle is closed by a cover 9 whose flanges 10 fit closely the side wall of the receptacle. These flanges 10 are deep enough to extend practically the full depth of. the receptacle so that they form covers for the channels 8. The movement of the vehicle causes the oil to surge. and splash siiiiicieiitly to be deposited in the upper end of" the channels, when it runs down onto toe curved ends? of: the clip. From. the ends of the clip, the oil seeps into the joints betweenthe leaves of thespring. By my construction, the oil is led directly onto the distributing-lip of the clip and is thus prevented from being jounced or blown about on the top surface of the spring. The covering of the channels 8 by the flanges of the cover insures the direct delivery of all the oil onto the distributing-end of the lip.

The cover is provided with an oil-hole 11.

This hole is closed by. a spring device 12 enclosed within the receptacle. This spring device consists of a fiat spring folded upon itself to approximately a normal V-shape.

One member rests upon the bottom of the receptacle and the other normally presses against the under side of the top of the cover, thereby keeping the oil-hole normally closed. When the spout of an oil-can is inserted in the oil-hole, the spout forces the spring away from the hole and permits the oil to be deposited in the receptacle. This construction enables me to employ a spring so long that it cannot be flexed beyond the limit where it would break down, so that, even tho the spout be inserted in the receptacle to the limit, the top member of the s 'n'ing will always come back to closure position. To insure proper positioning of the spring under all conditions, I make a hole in the lower member, into which one of the rivets 6 enters. As shown .in Figs. 2 and l, the rivet-head loosely enters the hole, but, as shown in Fig. 5, I may rigidly anchor the lower member to the bottom of the box by means of the rivet 6. As shown in- Fig. 6, the channel 8 may he formed in the cover wall instead of in the wall of the receptacle.

hat I claim is:

1. A spring oiler embodying a receptacle haw'in'g a top and a bottom wall and means for attaching it to aspring, said receptacle having a hole in its top, and a closure for said hole consisting of a fiat spring entirely enclosed within said receptacle and supported upon itself and tensioned between the top and bottom of the receptacle, the lower member of the spring being provided with a hole into which extends an upward projection of the bottom of the receptacle to thereby properly position the spring in the receptacle.

2. A spring oiler embodying a receptacle having a top and a bottom wall and a clip for clamping it to a spring, the receptacle and the clip being riveted togethen the head of the rivet extending up into the receptacle, said receptacle being provided with a cover having a filling-hole, and a. closure spring for said hole consisting of a folded flat spring entirely enclosed within said receptacle and tensioned between the cover and the bottom of the receptacle and having a hole fitting over said rivet-head, for the purpose set forth.

3. A spring oiler embodying a receptacle and means "for attaching it to a sprin a cover for said receptacle having a wall fitting down over the upstanding wall of the receptacle the full depth thereof a vertical channel being formed between said overlapping walls having its upper end open to the interior of the receptacle and'its lower end open to the exterior thereof.

4. A spring oiler embodying a clip, a receptacle attached thereto and hav ng vertical channels in its end Walls, and a cover for said receptacle having a flange extending to the bottom of said channels to thus entirely close the channels except at their lower, delivery ends.

In testimony whereof I hereunto afiix my signature.
